The present invention relates to new and useful improvements in rivetloading devices designed primarily for loading airplane rivets inspecially designed holders -for `use in magazine riveting machines.

-An important object of the invention is to provide a rivet loadingtable having means for vibrating the table and guiding the rivets into auniform position for feeding into the holder, and in which-any desirednumber of the holders may be loaded simultaneously and selectivelyremoved `and placed in the riveting machine.

A further object is to provide a loading device of this character ofsimple and practical construction which is efcient and reliable inoperation, relatively inexpensive to manufacture `and otherwise welladapted for the -purposes `for -which the same is intended.

Other objects and advantages reside in the details of construction andoperation as 'more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likereference numerals refer to like parts throughout, and in which Figure 1is a top plan view,

Figure 2 is a side elevational view,

Figure 3 is a rear end elevational view,

Figures 4, 5, 6, 7 and 8 are sectional views taken on lines 4 4, 5 5, 66, 'I 'I and 8 8, respectively of Figure 1.

Figure 9 is a fragmentary elevational view of the end gate,

Figure is a fragmentary sectional view of the table showing the end ofthe rivet channels, and

on a line Il l I of Figure 1.

Referring now to the drawings in detail, the numeral 5 designates a baseframe having a plurality of spaced parallel horizontal rods 6 on whichlegs 'I are slidably mounted by means of collars 8. The upper ends ofthe legs support a table 9 which is reciprocably vibrated on the rods 6by means of an electric motor I0 and pitman II suitably connected to themotor and to a depending leg l I to accomplish the desired reciprocatingmovement of the table as shown by the arrows at the left of Figure 3.

The table 9 is inclined in a direction transverse to its movement andalong the upper edge of the table is supported a trough-shaped hopper I2adapted to receive the rivets and discharge the same on the surface ofthe table from side to side thereof.

The surface of the table at its intermediate.

Figure 11 is a fragmentary sectional View taken o portion is formed withspaced tapering channels I3, the sides of which are shaped to provideshoulders I4 adapted to support the heads I5 of the rivets and with theShanks I6 thereof suspended in the channels. The lower end'of'the tableis offset below the surface of the upper end and extending transverselyof the lower portion is a plurality of rods I'I adapted to supportaplurality of rivet holders I8 by means of hangers I9 having verticallyinclined notches 2l!v iny one edge to engage the rods I'I.

The holders I8 are formed of a plurality of spaced parallel rods 2|.arranged in the form Vof an inverted V in cross section, the rods beingrigidly connected toeach other by the hangers I9 as well as by spacingmembers 22 as shown in Figure 4, the hangers and spacing members 22being properly positioned so as not to interfere with the passage of therivets along the rods forming the holders or magazines.

One end of the holders I8 issupported in alignment with the channels I3lto receive the rivets from the channels so that one rod will lie onlthe head of the rivets while the other two rods will support the underside of the head -of the rivets and with the shank of the rivetssuspended ibetween the rods, as shown to advantage in Figure 5.

The holders are supported in an inclined position, as shown in Figure 4,so that the rivets will slide toward the lower end of the holders andare held thereon by a cap 23 threaded or otherwise removably secured tothe lower ends of the rods ZI.

A hinged end gate 24 is secured to the lower end of the table tofacilitate removal of the holders from the rods Il, the gate beingyieldably held in an upright or closed position by springs 25.

A rivet collecting trough 26 is attached to the underside of the tableat its lower end to retrieve any of the rivets dropped from the holders,or which accidentally drop from the channels I3.

After the loaded holders are removed from the table, they are placed ina riveting machine of a type disclosed in my -co-pending applicationfiled of even date herewith.

The rods 2I forming the rivet holders are preferably round in crosssection to reduce friction at the point of contact thereof with therivets, although it will be understood the rods may be of any desiredshape.

It is believed the details of construction, operation and manner of useof the device will be readily understood from the foregoing withoutfurther detailed explanation.

Having thus described my invention, what is claimed as new is:

1. A rivet loading apparatus comprising a loading table adapted toreceive a quantity of loose rivets, guide means in the surface of thetable adapted for positioning the rivets upright, a rivet magazinehaving one end open, means carried by the table for closing the upperend of the magazine, and hangers carried by the magazine adapted forengagement with a part of the table for detachably supporting themagazine in an elevated position with its open end abuttingeone edge ofthe table in alignment with the guide means to receive rivets from thelatter.

2. A rivet loading apparatus comprising a loading table adapted toreceive a quantity of loose rivets, a guide channel in the surface ofthe table having shoulders at each edge adapted to support the heads ofthe rivets with the shanks thereof suspended in the channel, a rivetmagazine having one end open, means carried by the table for closing theupper end of the magazine, and hangers carried by the Vmagazine adaptedfor engagement with a part of the table for detachably supporting themagazine in an elevated position With its open end abutting one edge ofthe table a rivet magazine, and hangers carried by the magazine adaptedfor engagement With a part of the table for detachably supporting themagazine in an elevated position With one end of the magazine inalignment with the channel to receive rivets from the latter. Y

3. A rivet loading apparatus comprising -a loading table adapted toreceive a quantity of loose rivets, guide means in the surface of thetable adapted for positioning the rivets upright, a rivet magazineandhangers carried by the magazine adapted for engagement with apart of thetable for detachably supporting the magazine in an elevated positionwith one endk of the magazine in alignment with the guide means toreceive rivets from the latter, said magazine ycomprising spacedparallel rods rigidly secured to each other.

4. A rivet loading apparatus comprising a load ing table adapted toreceive a quantity of loose rivets, a guide channel in the surface ofthe table having shoulders at each edge adapted to support the heads ofthe rivets with the Shanks thereof suspended in the channel, a rivetmagazine comprising ya plurality of spaced parallel rods rigidly securedto each other, and means for supporting the magazine in an elevatedposition with one end of the magazine in alignment with the channel.

5. A rivet loading apparatus comprising a table, means for supportingthe table in an inclined position, means for vibrating the table, aguide channel in the surface of the table adapted to receive and supportrivets by their heads in an upright position, a rivet magazine, hangerrods carried by the table, and hangers ycarried by the magazine fordetachable engagement with said rods for removably supporting themagazine in an elevated position with one end of the magazine inalignment with the channel to receive rivets therefrom.

6. A rivet loading apparatus comprising -a table, means for supportingthe table in an inclined position, means for vibrating the table, aguide channel in the surface of the table adapted to receive and supportrivets by their heads in an upright position, a plurality of rodsextending transversely of the table, a rivet magazine, and hangerscarried by the magazine for removably supporting the magazine on therods in an elevated position with one end in alignment with saidchannel.

'7. In combination, ya rivet loading table, and a rivetmagazinecomprising a plurality of spaced parallel rods in triangular crosssectional arrangement and adapted to engage the top and bottom surfacesof the head of aV rivet, supporting means carried by the table, andsuspension means Icarried by the rods for detachably supporting themagazine on the table in an elevated position to feed rivets in anupright position from the table to the magazine.
